Gosh where to start. I'd start by crating her more. Whenever you cannot work with her. So her day would be like, crate (overnight) take outside in the AMs on a leash.
Then after you take her outside ON A LEASH, walk with her around and bring her back inside, crate her and feed her (in the crate).
Then you go to work or whatever. Come home, leash her and take her outside. Don't LET her get to the point of running away from you. While on the leash (and it should be about 10 ft. long) call her and reel her in. Praise her for coming back to you (even though you reeled her in).
Right now she doesn't sound like she knows what to expect from you.
And you say "grab her" -- whenEVER you call her at this point, she should be leashed so she has to come. Praise and/or treat her for coming.
This is just until you can get her into classes. Honestly, you sound like a very loving and caring person with your dogs but you need to get this under control now.
From your description she could easily become a fear biter.
I dunno what the deal is, it seems like you and I are the only ones online this AM

But I'm anxious to hear what, MnP13 has to say, for instance, I have a great deal of respect for her methods of training and will link her to this discussion.
